Troubleshooting Cloudflare domains blocked by China

Determine if your Cloudflare site is blocked by the Great Firewall of China.


To confirm the Cloudflare IPs associated with your domain are blocked in China, provide the following details to Cloudflare Support:

1. A traceroute to your domain from a location in China to demonstrate the network path. 

2. The results from the Great Firewall Checker.

3. DNS resolution response for the domain from a location in China.  Consider using a tool like DNS Checker.

4. The type of content hosted on your site.  China does censor certain content including pornography, gambling, and specific types of political discussion.

Cloudflare Support can only confirm if a domain is blocked by China and has no control over unblocking.
